Abstract

Patente de Invenção: MéTODO E EQUIPAMENTO PARA ESTABELECER SERVIçOS TDD/TTY ATRAVéS DE CANAIS VOCODIFICADOS. Um método e equipamento para estabelecer serviço de comunicação de baixa atividade através de canais vocodificados em um sistema digital de telecomunicações, que pode incluir links sem fio. Em uma modalidade, uma vez que o sistema de telecomunicações receba um sinal de comunicação de baixa atividade (402), todos os vocodificadores automaticamente se "travam"em uma taxa total (404) em preparação para a transmissão. Quando for o caso, a potência de transmissão do sinal de comunicação de baixa atividade é ajustada para reduzir a taxa de erro de quadro (408). Ajustes dinâmicos são efetuados continuamente durante a transmissão (412). O sistema de telecomunicações inlcui equipamentos para sensoriar a presença do sinal de comunicação de baixa atividade.
